One sole baptismal sign,
One Lord below, above,
Zion, one faith is thine,
One only watchword—love;
From different temples though it rise,
One song ascendeth to the skies.

Our Sacrifice is one,
One Priest before the throne,
The slain, the risen Son,
Redeemer, Lord alone;
And sighs from contrite hearts that spring
Our chief, our choicest offering.

O may that holy prayer,
His tenderest, and His last,
His constant, latest care,
Ere to His throne He passed,
No longer unfulfilled remain,
The world’s offense, His people’s stain.

Head of Thy Church beneath,
The catholic, the true,
On all her members breathe
Her broken frame renew;
Then shall Thy perfect will be done,
When Christians love and live as one.
